HAND-SCRAPEB.

Application filed April 8, 1916.

To all whom it may comwm:

Be it known that I, JOHN L. WILGOX, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Hand-Scrapers, of which the following is a specification.

This invention relates to improvements in a tool designed primarily to scrape wood before finishing.

The object of the invention is to provide an elongated tool, the body portion of which constitutes a handle, and a means for hollding and clamping a blade in the free enc.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claim.

In the drawing, Figure 1 is a perspective view of my improved scraper. Fig. 2 is a central vertical section of the same. Fig. 3 is a transverse section on the line ww of Fig. 2.

The same numerals refer to like parts in all the figures.

1 indicates a body portion, preferably of wood, the rear end of which is shaped to form a convenient grip 2, while the opposite end is formed with a horizontal slit, indicated at 8, to provide upper and lower clamping jaws 4 and 5. The free ends of the jaws 4 and 5 are beveled, as shown at 6, the purpose of which will be obvious.

Below the body portion and adjacent the rear end of the slit 3, is a transverse groove 5 and above the same and formed in the upper surface of said body portion is a transverse slit 6. The slit 6 acts to weaken the wood and to form a fulcrum for the upper jaw 4, for a purpose to be described.

Seated in the groove 5 is the horizontal portion 7, of a yoke 8, the vertical portions 9, thereof, extending upwardly beyond the upper surface of the body portion, and are connected by a rod 10. Fitting under the rod 10, and extending beyond and behind same, is a clamp 11, the front end of which engages the top surface of the jaw 4, at a point intermediate the free end thereof, and the slit 6. In the rear end of the clamp is a threaded opening 12, in which engages a thumb screw 13, the end of which engages the top surface of the handle portion.

To properly position the clamp with ref- Specification of Letters Patent.

movement, while, as previously stated, the

rear edge of the blade abuts against the rear wall of the slit. The blade therefore is held rigid, longitudinally with the body portion,

and is also held against lateral movement when the clamp is operated.

The blade having been properly positioned, the thumb screw 13, is adjusted, because of the rod 10, acting as a fulcrum, the front end of the clamp bears on the upper jaw 4: and bends same toward the jaw 5, and efiectually clamps the blade between said jaws. The slit 6, readily permits of the jaw 4E yielding sufficiently under the pressure exerted by the forward end of the clamp. As the movement necessary to accomplish the desired result is but slight, obviously liability of the body portion breaking at the fulcrum point is remote.

The action incident to exerting pressure on the jaw 45, by the clamp, the yoke 8 is drawn up tight against the body portion, and as the rear end of the blade is confined by said yoke, it is also clamped tight at this point.

To release the blade it is only necessary to release the thumb screw, which releases the yoke and the clamp, with the result that upper jaw 4, assumes its normal position and the blade can be withdrawn.

By the construction described I have provided a simple scraper construction, and one which can be economically made. The body portion comprising the handle and the blade holder permits of the use of a single piece of material, and also permits of the slit at its opposite end to provide a-pair of jaws, the upper surface of the body portion adjacent the rear end of the slit having a transverse slit, a blade fitted in the horizontal slit and abutting against the rear Wall of the latter, and blade holding means including a clamp, one end of which engages the surface of the upper aw in front of the transverse slit, and a screw at the opposite end of the clamp and engaging the upper surface of the handle to cause the 10 front end to bend the upper jaw and clamp the blade in position in the horizontal slit.
